A gene is a basic unit of heredity in a living organism that normally resides in long strands of DNA called chromosomes. Genes are coded instructions that decide what the organism is like, how it behaves in its environment and how it survives.
Genes are sections of DNA. A single gene is marked in Figure 1.1.6. Each chromosome can have over 1000 genes. The difference between one gene and the next is the:â¢ order of bases along the DNA strandâ¢ length of the DNA strand.The order of the bases along the DNA strand is the genetic code..1 DNA the molecule Organisms on Earth have many differences. Not many people would confuse an elephant with an earthworm, a tree with a tarantula or a penguin with a python. However, at one level the differences between organisms are not as great as you might think.
